The Role of the Electronic Transactions Act (ETA) in Electronic Signing

Singapore’s Electronic Transactions Act (ETA) provides a legal foundation for electronic transactions, including electronic signing. The ETA grants legal recognition to electronic signatures, ensuring that they hold the same legal validity as traditional handwritten signatures, provided they meet certain criteria. This legal recognition instils confidence in businesses regarding the enforceability and admissibility of electronically signed documents in court.


Secure Electronic Signature Criteria

To be considered legally valid and secure under Singapore’s ETA, an electronic signature must fulfil the following requirements:

  • Unique association with the signer: The electronic signature should be exclusively connected to the signer, ensuring that it cannot be utilized by anyone else.
  • Reliable identification: The signature must reliably identify the signer and ensure the integrity of the signed document.
  • Sole control of the signer: The electronic signature should be generated using a method under the exclusive control of the signer, without the possibility of external tampering or manipulation.
  • Detection of subsequent alterations: The electronic signature must be attached to the document in such a manner that any changes made to the document after signing will be evident and invalidate the signature.
  • The certificate was issued by an accredited certification authority


Selecting an Accredited Digital Identity Provider

To guarantee legal compliance and trustworthiness, it is essential to choose a digital identity provider accredited by Singapore’s Infocomm Media Development Authority (IMDA). Accredited providers, like Netrust, have undergone a stringent evaluation process to ensure their services meet the highest standards of security, reliability, and compliance with local regulations.



Becoming familiar with the legal framework of electronic signing in Singapore is essential for businesses to ensure compliance and build trust with partners and clients. The Electronic Transactions Act (ETA) governs electronic signing, and selecting an accredited digital identity provider is crucial for maintaining legal validity.
